Scale Parameters
The scale parameters configure IDS440 for the weigh platform or load cell that it is
connected to. The preceding table titled “SCALE PARAMETERS” lists the scale
parameters and their factory settings. Use the “Field Setting” column to record any
changes made to the factory default values.
Many of the following parameters are entered in terms of “graduations”. The full-scale
graduations can be found by dividing the full-scale weight by the count-by weight. For
example, if the scale is configured for 500.00kg x 0.05kg, the full-scale graduations is
500.00/0.05 = 10,000 graduations to full scale.
The numbers in parenthesis are the default factory settings.
Parameter 1. Load Cell mv/V (3 mv/v)
The IDS440 can be used with load cell outputs of 1 mv/V, 2 mv/V, or 3 mv/V. Enter a 1,
2, or 3 for the load cell type used in your application.
Setting A/D gain
0 200
1 mV/v 100
2 mV/v 100
3 mV/v 50

Parameter 2. Digital Filter (9)
The digital filter removes scale vibrations and other noise signals from the weight
display. The filter range is between 0 and 18. A setting of 0 provides no filtering; a
setting of 18 provides maximum filtering. The higher the filter number, the longer the
settle time of the weight display. For example:
Filter Setting Settle Time
3 0.4 sec
6 0.8 sec
9 1.75 sec
12 3.5 sec
15 7.0 sec
Use the smallest filter setting that provides satisfactory display stability.
Parameter 3. Display Update Rate (1)
Enter the time between display updates (in tenths of a second). An update rate of 1
causes a 0.1 second delay between display updates, a rate of 200 causes a 20 second
delay between updates. NOTE: motion detection is calculated using the weight values of
the display rate. If the update rate is 50, the motion calculation is based on weight
readings sampled at 0.5sec intervals.
